TITLE: Alarm time for fluoride levels in Mackay’s water
STATUS: No response
UPDATES: Please post all updates and comments in the LEAVE A REPLY section below.
Mackay’s fluoridated water imbibers should be aware of the following and consider the implications of drinking large amounts of fluoridated water.
The target level for fluoride in Mackay’s public water supply is 0.5 to 0.8 milligrams per litre (mg/L).
Queensland’s fluoridation code of practice requires a ‘High Alarm’ if the fluoride level exceeds 0.9 mg/L.
At a level of 1.1 mg/L it is ‘High High Alarm’ time.
It is ‘Critical Alarm’ time when the fluoride level in water reaches 1.3 mg/L.
1.0 mg/L/F is equal to 1 ppm/F.
Fluoridated toothpaste contains from 500 to 5,000 ppm/F.
It is likely that the ‘safe’ ingested fluoride limit is exceeded on a daily basis by most people because fluoride can be absorbed through the mucous membranes in the mouth.
